Gustard X26

 • The X26 uses two ESS Technology's flagship audio DAC chip ES9038PRO for dual mono audio digital-to-analog conversion. Each channel uses a separate ES9038Pro chip, and each channel is completely independent power supply and grounding for best performance.

• The X26 uses the GPLL-M1 high-precision phase-locked loop module with ultra-low residual phase noise, and the recovered audio clock can reach the femtosecond level of ultra-low jitter. Thanks to the complex algorithm, the jitter suppression performance is excellent, and the additional jitter introduced by various factors can be easily solved;

• The X26's audio digital signal processing is implemented with the Analog Device SHARC digital audio DSP, equipped with Gustard's proprietary high-performance anti-aliasing noise algorithm, which uses a high-precision floating-point 64-bit algorithm for some key digital signal processing. This algorithm has been optimized for ESS Technology DACs to ensure high sound quality;

• The X26 uses the CPLD programmable logic chip, which is equipped with Gustard's self-developed multi-year custom digital logic functions, including clock management, 2nd PLL digital shaping, DOP decoding, PCM/DSD depop switch and other exclusive technologies, which lays a solid foundation for excellent sound quality. ;

• The X26 uses two high-quality audio dedicated toroidal transformers to power the digital and analog circuits, thus achieving complete independent power supply without mutual interference;

• The X26's analog circuitry uses a native fully balanced architecture with no single-ended/differential conversion for complete balanced and single-ended output;

• The X26's analog LPF circuit uses a self-developed discrete circuit, and the parameters of each stage of the circuit have been carefully adjusted to achieve the best operating point;

• X26 supports 0dB~-90dB, a total of 90 gears of digital volume, with the included high-quality remote control to easily adjust the volume;

• All digital inputs of the X26 support DSD:

IIS: DSD64, DSD128, DSD256, DSD512;

SPDIF, AES/EBU: DSD64, DSD128 (DOP mode)

Optical: DSD64 (DOP mode);

USB: DSD64, DSD128, DSD256, DSD512 (DSD native Only);

• The X26 is equipped with three digital filter algorithms developed by Gustard and can also be turned on.

PCM: VIVID (recommended) / COMPOSITE / GENTLE;

DSD: 47K/50K/60K/70K;

NOS mode: (only sampling rate of 176.4KHz and above can be used), NOS (No OverSampling) does not perform digital oversampling, directly digital-to-analog conversion of the original digital audio signal. This mode is recommended for use with audio player software such as HQplayer with its own oversampling digital filter function;

• X26's USB digital audio interface module uses ESS Technology's USB AUDIO solution, up to PCM768K DSD512;

• The X26's screen brightness is adjustable and it is automatically remembered after 10 seconds of no operation. After power-on, it will automatically maintain the settings before the last power-off, and humanized operation control;

• The X26 features a brushed aluminum chassis with optional colors including silver (matte white) and black;

• X26 chassis size: width 330* depth 260* height 65MM (excluding protruding parts);

• X26 package size: length 420 * width 360 * height 175MM;

• X26 package weight: 7KG;

• The X26's AC supply voltage mode can be manually switched between 110/115V and 220/230V;

• X26 XLR interface definition: US standard (1 ground, 2 hot, 3 cold)
